Actionscript 3 :: Properties Null At Component Drawing Time?
Feb 23, 2012
I have got problem accessing a property of a component. I want to use this property to decide whether to include a particular child component.
For example:
MyMainView.mxml lists this component
<view:AnotherView id="anotherView" aPresenter="{thePresenter}"/>
Now AnotherView.mxml has a property
<fx:Script><![CDATA[
[Code]......

I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?

I have a component with a public variable declared
[Bindable]
public var mnuSource:String;
When I extend this component, I can reference mnuSource (it compiles) but Runtime complains about the property not being accessible (error 1056).
How do you modify / declare component properties so they are actually available to other components?

Yet another woe with the AdvancedDataGrid - this time, with the AdvancedDataGridEvent. It seems that when listening to the ITEM_EDIT_END event, several of the event properties are returned null. I've been getting null for event.column, event.item, etc.

I've written the following custom component, SubNavBar.mxml:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" height="100" width="300"
creationComplete="init()">
<mx:Script>
[Code]...
Whenever the trace function runs in init(), the property menuItems returns null. I don't seem to have this problem with other variable types, like Boolean or String. Is this due to the size of the XMLListCollection object? How can I set up this SubNavBar custom component with XMLListCollection property and bind it to a control in the component?

I've loaded a video into the FLVPlayback component and I'm looking for a way to get the total time and the time played so far and output them to two text fields so the end result would look something like "00:12/00:50".
Right now I'm defining the video by the components inspector but I'm eventually hoping to define this bit by actionscript as well.

I have a small problem with ActionScript in a SWF file I'm creating. It is a ScrollPane component where I want lo upload multiple buttons with links to Web pages. I have everything prepared, a ScrollPane created and buttons as well (about 30). What I cuden't find is how to locate the buttons on stage with the properties X and Y, how introduce the properties for each of the buttons. I still do not handle well ActionScript and the manual I have is very basic.

I'd like to create some kind of component's properties inheritance to create generic behaviors in my component.Imagine I work a lot with textfield based components (counters, animated text... and so on), I'd like my artist to custom these components without being scared by the "update" button. Today, when component's code is updated, my artist has to update every flas using these components, and all of them are re-set to original look (if he had customed font color, or font size by duplicating the component instance, everything is set back to the current look of component).
That's why I'd like to know if there is a way for a component to inherit some of its properties and behaviors from another component class ?

Over the weekend i put together an MP3 player in Flex and just managed to figure out the SoundSpectrum.
It is working as expected.
I am facing problems when it comes to using a bitmap.
Right now, my "Analyser" class pulls the data from SoundMixer.computerSpectrum.
I then use that data with the drawing API to create a simple analyser. You know, just spikes.
Here is the code for that part:
Code:
private function update(e:TimerEvent): void
{
SoundMixer.computeSpectrum(ba, true);
var n:Number = 0;
[Code]....
Ok using common sense here, I am telling flash to take a snapshot of the Analyser and draw it to the bitmapData.
However, i cant seem to get this working. I am not using the dispose() method to clear the bitmap so id expect to see a mess of points (similar to if i removed the g.clear()) but nothing happens.

I've exhausted searches looking for how to add properties to the component properties panel for a custom AS2 and AS3 components.This Adobe Livedoc suggests using Inspectable tags before variables:[URL]I've also tried adding the components via the Component Definition dialog in the library.Both methods work in that they produce an .swc, but neither adds the properties into the Component Properties.

(Actionscript 2 btw - and actually cs4, not that it really makes any difference?) I have a class that instantiates a movieclip from the library, e.g.:
Code:
debugbar:MovieClip = thing.AttachMovie("debugbar", "debugbar_mc", 999);
So attaching it to the where ever "thing" is - could be movie clip or level0 or whatever, doesn't matter as "debugbar" is a private variable of the class. Now the important part - debugbar in the library is a movieclip that contains some components - buttons and textInputs. The problem comes when trying to access these components.
I would have thought that this would work:
Code:
debugbar.input_txt.text = "hello";
In order to set the text of "input_txt", the instance name of a TextInput component on the timeline of the movie clip (put there in author time). However, this does not work. Infact, I cannot access any specific "component" properties - they come back undefined. I can however set and retrieve MovieClip properties for the "input_txt", such as _x. However there is one added strange thing with this too - setting _visible to false doesn't seem to work (however perhaps a component by default overrides this).
I also appear not to be able to add event handlers to the component - at least for the usual component events. I tried casting it to a component, such as:
Code:
var temp:TextInput = TextInput(debugbar.input_txt);
trace(temp);
which gave "temp" as null.
However if you trace the thing itself without casting to what it is, it gives the path to correctly. It almost seems like the components are somehow broken when trying to access them this way - or that they cannot be accessed this way?
The thing is, I was able to access all of this before, when the code to do it was placed on the timeline (frame 1, the only frame) of the debugbar itself, where the components were child instances. This meant I could just reference them directly too - so input_txt rather than debugbar.input_txt , although that is probably largely irrelevant. I need to have it in a class though, as I need to pass in certain objects that need to be accessed by the mc.

i'm working on a drawing tool with the flash drawing methods, but my movie starts to slow down. i'm storing the variables in an xml object and then looping through them onEnterFrame. right now i'm limiting the amount of lines that are drawn to 50. anyone have any tips on speeding up the drawing methods. as i understand it they are the same methods that flash uses to draw all it's lines. shouldn't it be able to render more than 50lines at a time.

I created a movie clip symbol with a user interface in it, using the standard components. It contains various components that I draged on the stage. I named the instances (e.g titleLabel). Then I created an ActionScript class for that user interface. Under the linkage properties of the symbol I specified that class. In the class itself, i declared the attribute "var titleLabel:Label". I thought this would be the same instance from the symbol? But: Trying to set the text of the Label AFTER the movie was dynamically added to the parent does not work. I cannot access any properties.
Here is the example:
My Class for the user interface:
Code:
import mx.controls.*;
class Information extends MovieClip {
var titleLabel:Label; //this is the same instance name as in the symbol
